I own a 3006 and 300 Ultra mag and yes they do have some recoil but nothing like the old single shot 12 gauge that my grandfather owns...can't remember make & model but wow that beast kicks....
My ultra mag does now have a muzzle break but I have shot it before it was installed and it was still managable just wanted to make it a bit more shooter friendly. I can now shoot the ultra mag all day long.....
